Technical Field

[0001] The utility model relates to the technical field of design and manufacturing of automobile key chains, in particular to a safe hidden screw-free leather strap automobile key chain. Background Art

[0002] Leather car key chain, as a common car accessory, is mainly used to hang and carry car keys.

[0003] In the existing car keychain design, in order to improve the user experience, screw-free design has gradually become a trend. This type of design usually uses a snap-on connection to achieve the fastening connection between the keychain components, thereby avoiding the cumbersome use of screws. However, this snap-on connection design has some problems in practice:

[0004] 1. In order to ensure the firmness of the connection, the strength of the snap-on connection often needs to be designed to be relatively high. This not only makes it difficult to install, disassemble and replace parts, but also usually requires the use of special stamping equipment during the manufacturing process, resulting in relatively high manufacturing costs.

[0005] 2. When a structure that is relatively easy to connect and disassemble is used, although the convenience of use is improved, the firmness of the connection is often difficult to ensure, which may cause insecurity and lead to loosening and loss during long-term use.

[0006] Therefore, how to reduce the manufacturing cost and improve the convenience of installation, disassembly and replacement of parts while ensuring that the parts of the leather strap car key chain will never fall off due to misoperation has become a technical problem to be solved by the utility model.

The diameter of the part of the limit clamping hole 3 near the other end of the hole is reduced so that the limit clamping hole 3 forms a small hole 18 at the other side of the lower metal block 11.

[0047] Embodiment 1:

[0048] This embodiment provides a safe, hidden, screw-free leather strap car key chain, the specific structure and usage of which are described as follows.

[0049] The key chain mainly comprises a key chain body 1, a pivoting buckle 2, a limit card hole 3, a positioning plate 4, a belt limit hole 5, a latch column 6 and a positioning sleeve 7. The key chain body 1 is composed of a metal buckle 8 and a belt 9, and the metal buckle 8 comprises an upper buckle ring 10 and a lower metal block 11.

[0050] The pivoting fastener 2 is rotatably matched with the lower metal block 11 through the rotating shaft, and can be switched between a blocked state and an open state. In the blocked state, the metal buckle 8, the lower metal block 11 and the pivoting fastener 2 together form a closed loop, at which time the insertion end opening of the limit card hole 3 is hidden and blocked by the pivoting fastener 2, ensuring that the key chain will not fall due to misoperation during use, thereby improving the safety of use.

[0051] When the belt 9 needs to be installed on the keychain body 1, the pivoting fastener 2 is first rotated to the open state, at which time the closed ring is opened and the insertion end opening of the limit card hole 3 is exposed. Next, the belt positioning group (composed of the belt 9, the positioning sleeve 7 and the positioning plate 4) is inserted into the bottom end of the lower metal block 11 through the belt limit card hole 5. Then, the latch column 6 is passed through the exposed insertion end opening of the limit card hole 3, and is engaged with the positioning sleeve 7 and the limit card hole 3, so that the belt 9 is firmly fixed on the keychain body 1.

[0052] In order to further improve the convenience and safety of the key chain, the present embodiment also adopts the following design: a spring 13 is arranged in the spring 13 cavity of the lower metal block 11, and one end of the spring 13 acts on the pivot fastener 2 to provide an elastic force to keep it in a blocked state. When it is necessary to install, remove or replace the belt 9, it is only necessary to overcome the elastic force and turn the pivot fastener 2 to the open state to engage or remove the latch column 6 with the positioning sleeve 7 and the limit clamping hole 3. When it is necessary to disassemble, press the pivot fastener 2 by hand, use a thin rod to push the latch column 6 out of the small hole 18, and then pull out the belt positioning group to complete the disassembly, so as to facilitate replacement, make installation, disassembly and replacement of parts simple and convenient, and ensure that the key chain will not loosen or be lost during normal use.

[0053] In addition, the shape of the latch post 6 matches the shape of the position limiting hole 3 to ensure that the two can fit closely and provide sufficient connection strength. The diameter of the portion of the position limiting hole 3 near the other end of the hole is reduced to achieve the use effect of limiting, and the insertion end of the latch post 6 is provided with an annular hole 14 and an annular sealing ring 15. When the latch post 6 is inserted into the position limiting hole 3, the annular sealing ring 15 is engaged with the reduced diameter portion of the position limiting hole 3, thereby further enhancing the firmness and sealing of the connection.

[0054] At least two clamping columns 16 are respectively provided on the front and back of the positioning plate 4, and clamping holes 17 matching with the clamping columns 16 are provided near the two ends of the belt 9. The belt 9 and the positioning plate 4 can be firmly connected together by clamping the clamping holes 17 and the clamping columns 16. At the same time, the clamping columns 16 and the positioning plate 4, as well as the positioning plate 4 and the positioning sleeve 7, all adopt an integrated structure to improve the overall structural strength and stability. Arc transitions are also provided at each corner to prevent safety hazards such as scratches or bumps during use.

[0055] To sum up, the safe hidden screw-free leather strap car key chain provided in this embodiment not only has the advantages of simple structure, easy installation and disassembly, and firm connection, but also can effectively prevent the key chain from falling due to misoperation, which is beneficial to improve the cost performance and market competitiveness of the product while reducing manufacturing costs.

[0056] Embodiment 2:

[0057] The present embodiment provides a safe, hidden, screw-free leather strap car key chain, the innovation of which is to utilize a pivotable fastener 2 on the key chain body 1 as a blocking structure, thereby ensuring that the key chain will not loosen or fall off without human intervention when the pivot fastener 2 is not manually moved.

[0058] Specifically, the keychain body 1 includes a metal buckle 8 and a belt 9. The metal buckle 8 is composed of an upper buckle ring 10 and a lower metal block 11. The pivoting buckle 2 is connected to the lower metal block 11 through a rotating shaft and can be freely switched between a blocked state and an open state. In the blocked state, the pivoting buckle 2 fits tightly on the lower metal block 11 to form a stable closed structure, which effectively prevents the keychain from loosening and falling off.

[0059] The cleverness of this design lies in that it utilizes the structure and movement characteristics of the pivot fastener 2 to achieve a fastening effect without screws or special fastening. When the user does not need to replace or adjust the belt 9, the user only needs to keep the pivot fastener 2 in the blocked state to ensure that the key chain will never loosen and fall off without human manipulation. This not only greatly improves the safety of the key chain, but also brings great convenience to the user.

[0060] In addition, when the user needs to replace or adjust the belt 9, the user only needs to switch the pivot fastener 2 from the blocking state to the open state to easily install, remove or replace the belt 9. When disassembly is required, the user presses the pivot fastener 2 by hand, pushes the latch 6 out of the small hole 18 with a thin rod, and then pulls out the belt positioning group to simplify the operation process, so that when the screw-free clamp connection is adopted, there is no need to tighten the clamp, which is convenient for replacement and ensures that it will never fall off.

[0061] In the present utility model, unless otherwise clearly stipulated and limited, the terms such as "installation", "setting", "connection", "fixation" and "screw-on" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. Unless otherwise clearly defined, ordinary technicians in this field can understand the specific meanings of the above terms in the utility model according to the specific circumstances.

[0062] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
